The sort of random number generator he is talking about, like reading 
/dev/random on Linux, is a cryptographic one and does generate random 
bit patterns that are measured in bytes.

That sort of function is generally pseudo random, although it might be 
seeded from a more random source.  It's not suitable for games, as 
suggested in the question, or security.

Incidentally the original was posted with a set of followup newsgroups 
that didn't include comp.protocols.time.ntp, so it is even possible that 
the questioner is not seeing these replies.
